Hi there,

Trying to add a second drive to an existing netbsd 2.0.2 Ultra1 box. Do I have a bad drive or is this just stupidity?

scsictl apparently not working with this drive :
# scsictl sd0 format
sd0: disk label read error
scsictl: failed to clean Unit Attention: Media Error, Medium Format
Corrupted


also, attempts at setting partitions with disklabel aren't taking:-
# disklabel -i sd0
sd0: disk label read error
partition> C
Automatically adjust partitions [no]: yes
partition> a
Filesystem type [?] [unused]: 4.2BSD
Start offset ('x' to start after partition 'x') [0c, 0s, 0M]: 0

8386)

I know that "the size of each partition must be a multiple of the number of sectors per cylinder (i.e., each partition must be an integer number of cylinders)", but aren't the above values correct since they are in cylinders anyway.


Possibly, for this drive the discrepancy between the 8387 cylinders, and the full drive of 8394 (as shown in the output below) may be a problem?:-
# disklabel sd0
sd0: disk label read error
# /dev/rsd0c:
type: SCSI
disk: mydisk
label: fictitious
flags:
bytes/sector: 512
sectors/track: 210
tracks/cylinder: 5
sectors/cylinder: 1050
cylinders: 8387
total sectors: 8813870
rpm: 7200
interleave: 1
trackskew: 0
cylinderskew: 0
headswitch: 0           # microseconds
track-to-track seek: 0  # microseconds
drivedata: 0

3 partitions:
#        size    offset     fstype [fsize bsize cpg/sgs]
 c:   8813870         0     unused      0     0        # (Cyl.      0 -
8394*)
disklabel: boot block size 0
disklabel: super block size 0


One more piece of the puzzle, looks like the drive isn't spinning up automatically - relevant lines from dmesg:-

I am now at a loss of how to add this drive to the U1, and any insights would be appreciated.

Many thanks,
Jonathan.
